基于ABAQUS显式动力分析建筑幕墙耐撞击性能

随着GB/T 38264—2019《建筑幕墙耐撞击性能分级及检测方法》的正式实施,相较于GB/T 21086—2007《建筑幕墙》中规范性附录F,对耐撞击性能的检测制定了明确的分级与检测方法,其中软重物撞击装置的轮胎数量由两个调整为三个。本文通过现场实验和ABAQUS显式动力分析研究建筑幕墙软重物撞击装置的变化对幕墙试件耐撞击性能的影响,对比分析试验数据和模拟数据,发掘准确实施检测的评价指标。

With the formal implementation of GB/T 38264-2019 classification and test methods for impact resistance of building curtain walls curtain walls,compared with GB/T 21086-2007 normative Appendix F of building curtain wall Appendix F of building curtain wall,a clear classification and detection method are formulated for the detection of impact resistance detection method are formulated for the detection of impact resistance.The number of tires of the soft weight impact device is adjusted from two to three is adjusted from two to three.Through field experiments and abaqus explicit dynamic analysis field experiments and abaqus explicit dynamic analysis,the influence of the change of soft weight impact device on the impact resistance of curtain wall specimens is studied of soft weight impact device on the impact resistance of curtain wall specimens is studied.Compared and analyzed the test data and simulation data to explore the evaluation indicators for accurate implementation of detection data and simulation data to explore the evaluation indicators for accurate implementation of detection.
